...and "stuck in a moment", the unique song rehearsed in Los Angeles that have never been played this tour.
That March 26th LA dress rehearsal is officially considered the first show of the Vertigo tour, as per Bono's announcement at the end of the show that it was not a rehearsal, that it was the first show. Since it was a show open to the genral public, which is how I got in (not being a contest winner), it was a full Veritgo show.
As a result, I consider Stuck to have been played once on this tour. I saw and heard it played with my own eyes and ears.
